SUPPORT FOR SPINNING-SPINDLES.

SPECIFICATION forming part Of Letters Patent No. {131,511, dated July 1,1890.

Application filed February 11, 1890- Serial No. 340,004. (No model.)

To all whom it may concern:

Be it known that I, GEORGE OTIS DRAPER, of l-Iopedale, county ofWVorcester, State of Massachusetts, have invented an Improvement inSupports for Spinning-Spindles, of which the following description, inconnection with the accompanying drawings, is a specification, likeletters on the drawings representing like parts.

In this my invention I have provided a sleeve-whirl spindle with acompound swiveled bolster composed of two parts, each having at itsouter side a rounded projection or enlargement to contact with theinterior of the supporting-case, one of said projections being above andthe other below the line of band-pull on the sleeve-whirl, the band-pullcoming between the two swiveled parts of the bolster.

Prior to my invention a bolster has been swiveled in the line of theband-pull, and so, also, a step has been swiveled.

By dividing the bolster into two swiveling parts and having the band-pull between them, which is feasible only when a sleeve-whirl is used,the entire bolster-bearing can be perfectly aligned with the spindle,which is very difficult to accomplish, owing to imperfections in bothspindle and bolster, especially when the bolster is in one piece.

Figure 1 in elevation and section shows a spindle and support embodyingmyinvention;

Fig. 2, an elevation of the compound bearing or bolster removed from thesupporting-case.

The supporting-case A rests on the rail 13 in the usualmanner. The lowerend of the posed of two parts a Z), each having an annular projection aor b, the projection a contacting with the interior of thesupportingcase at a point above the grooved or bandreceiving portion ofthe whirl and the line of the band-pull, while the projection 12 islocated below the line of band-pull; or the said projections are soarranged that the bandpull comes between them, the said projectionsacting independently as swlr el-bearin gs. The rotation of the part awith the spindle is restrained by the pin 13, and the projection 2 ofthe part b entering a notch in the part or acts to prevent rotation ofthe part b and also makes a joint between a and b; but the said partsmay be restrained from rotation in any usual manner without thisconnection without departing from my invention. As shown, the lower endof the part Z2 rests on a shoulder 4 of the bolster-case.

I claim 1. A sleeve whirl spindle, a supportingcase, and a compoundbearing made in two parts, each part having a projection to permit it toswivel in the supporting-case one above and the other below the line ofbandpull, substantially as described. v

2. The sleeve-whirl spindle, the supportingcase, and the two-partbearing jointed together, each part having an external annular 7oprojection to enable the said parts to swivel independently of eachother, substantially as described.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing Witnesses. I

GEO. OTIS DRAPER.
